The 3500 Sovran is very spacious, and every inch of its 35 feet is a Tiara. Like the 3900 and 4300 Sovran, the 3500 derives its abundant space (and comfort) from Volvo Penta® IPS technology … The IPS engines take up less space than traditional inboards, which Tiara reinvests in a wide-open practical floor plan, with great storage space. With a large open lounge/dinette/galley greatroom, aft theater room (convertible to 2nd stateroom), aft head with separate shower, and forward owners stateroom (with privacy curtain).
